SAFETY
INFORMATION
WARNINGS
WARNING: FIRE, BURN, INHALATION, AND EXPLOSION
HAZARD. KEEP SOLID COMBUSTIBLES, SUCH AS BUILDING MATERIALS, PAPER OR CARDBOARD, A SAFE DISTANCE
AWAY FROM THE HEATER AS
RECOMMENDED BY THE INSTRUCTIONS. NEVER USE THE
HEATER IN SPACES WHICH DO
OR MAY CONTAIN VOLATILE OR
AIRBORNE COMBUSTIBLES, OR
PRODUCTS SUCH AS GASOLINE, SOLVENTS, PAINT THINNER, DUST PARTICLES OR UNKNOWN CHEMICALS.
WARNING: NOT FOR HOME
OR RECREATIONAL VEHICLE
USE.
The heater is designed for use as a construction
heater in accordance with ANSI Z83.7/CGA
2.14. Other standards govern the use of fuel
gases and heating products for specific uses.
Your local authority can advise you about
these. The primary purpose of construction
heaters is to provide temporary heating of
buildings under construction, alteration or repair. Properly used, the heater provides safe
economical heating. Products of combustion
are vented into the area being heated.
We cannot foresee every use which may be
made of our heaters. CHECK WITH
YOUR LOCAL FIRE SAFETY AUTHORITY IF YOU HAVE QUESTIONS
ABOUT HEATER USE.
Other standards govern the use of fuel gases and
heat producing products for specific uses. Your
local authorities can advise you about these.
Carbon Monoxide Poisoning: Some
people are more affected by carbon monoxide than others. Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, and/or nausea. If you have
these signs, the heater may not be working
properly. Get fresh air at once! Check for
proper ventilation and have heater serviced.
Propane Gas: Propane gas is odorless.
An odor-making agent is added to propane
gas. The odor helps you detect a propane gas
leak. However, the odor added to propane
gas may fade. Propane gas may be present
even though no odor exists.
Make certain you read and understand all
Warnings. Keep this manual for reference.
It is your guide to safe and proper operation
of this heater.
• Install and use heater with care. Follow
all local ordinances and codes. In the
absence of local ordinances and codes,
refer to the Standard for Storage and
Handling of Liquefied Petroleum Gas,
ANSI/NFPA 58 and the Natural Gas Installation Code, CAN/CGA B149.2. This
instructs on the safe storage and handling
of propane gases.
• Use only the electrical voltage and frequency specified on model plate.
• The electrical connections and grounding of the heater shall follow the National
Electric Code, ANSI/NFPA 70, or Canadian Electrical Code, part 1.
• Electrical grounding instructions — This
appliance is equipped with a three-prong
(grounding) plug for your protection
against shock hazard and should be
plugged directly into a properly grounded
three-prong receptacle.
• Use only a three-prong, grounded extension cord.
• Use only the hose and factory preset
regulator provided with the heater.
• Use only propane gas set up for vapor
withdrawal.
• Provide adequate ventilation. Before using heater, provide at least a 1.5-squarefoot opening of fresh, outside air.
• Approved by the New York City Fire
Department under Certificate of Approval #4953. To be used only at construction site with applicable New York
City codes, regulations, rules, directives,
permits, etc.
• This product has been approved for use
in the Commonwealth of Massachusetts.
• This heater produces carbon monoxide,

a reproductive toxin under Proposition 65.
• For indoor use only. Do not use heater
outdoors.
2
• Do not use heater in occupied dwellings
or in living or sleeping quarters.
• Do not use heater below ground level.
Propane gas is heavier than air. If a leak
occurs, propane gas may sink to the lowest possible level.
• Keep appliance area clear and free from
combustible materials, gasoline, paint
thinner, and other flammable vapors and
liquids. Do not use heater in areas with
high dust content.
• Minimum heater clearances from combustibles:

• Check hose before each use of heater. If
highly worn or cut, replace before using
heater.
• Locate heater on stable and level surface
if heater is hot or operating.
• Not intended for use on finished floors.
• Never block air inlet (rear) or air outlet
(front) of heater.
• Keep heater away from strong drafts,
water spray, rain, or dripping water.
• Do not leave heater unattended.
• Keep children and animals away from
heater.
• Never move, handle, or service a hot,

This heater is designed to operate with a
minimum 20-pound propane tank. You may
need two or more tanks or one larger tank in
colder weather. Use a 100-pound tank for
longer operation or in very cold weather.
Less gas is vaporized at lower temperatures.
Your local propane gas dealer will help you
select the proper supply system. The minimum surrounding air temperature rating for
each heater is -20°F (-29°C).

6.
Provide propane supply system (see
Propane Supply, page 3).
Connect fuel gas fitting on hose/regulator assembly to propane tank(s). Turn
fuel gas fitting counterclockwise into
threads on tank. Tighten firmly using a
wrench. IMPORTANT: Position regulator so that hose leaving the regulator
is in a horizontal position (see Figure
6). This places the regulator vent in the
proper position to protect it from the
weather.
Connect hose to valve inlet. Tighten
firmly using a wrench. You must use
the regulator supplied with heater.
Open propane supply valve on propane
tank(s) slowly. Note: If not opened
slowly, excess-flow check valve on propane tank may stop gas flow. If this
happens, close propane supply valve
and open again slowly.
Check all connections for leaks. Apply
mixture of liquid soap and water to gas
joints. Bubbles forming show a leak
that must be corrected.
Close propane supply valve.

OBSERVED FAULT
POSSIBLE CAUSE
REMEDY
Fan does not turn when heater is plugged in.
1. No electrical power to heater
1. Check voltage to electrical outlet. If voltage is good, check heater power cord for
breaks
2. Adjust motor/fan guard to keep fan from
hitting inside of heater shell. Bend fan
guard if necessary
3. Replace fan. See Fan, page 9
4. Replace motor. See Motor, page 8
2. Fan hitting inside of heater shell
3. Fan blades bent
4. Defective motor
Heater will not ignite.
1. User did not follow installation or operation instructions properly
2. No spark at ignitor. To test for spark, follow step 9 under Ignitor, page 13. If you
see spark at ignitor, have heater serviced
by qualified service person. If no spark
seen:
A) Loose or disconnected ignitor wire
B) Wrong spark gap
C) Piezo ignitor loose
D) Bad ignitor electrode
Heater shuts down while running.
1. High surrounding air temperature causing thermal limit device to shut down
heater
2. Restricted air flow
3. Damaged fan
4. Excessive dust or debris in surrounding
area
1. Repeat installation and operation instructions. See Installation, page 5 and
Operation, page 6
2. A) Check ignitor wire. Tighten or reattach loose ignitor wire. See Figure 17,
page 9 for ignitor wire location
B) Set gap between ignitor electrode and
target plate to .17"
C) Tighten nut holding piezo ignitor to
base of heater
D) Replace ignitor electrode. See Ignitor, page 9
1. This can happen when running heater in
temperatures above 85°F. Run heater in
cooler temperatures
2. Check heater inlet and outlet. Remove
any obstructions
3. Replace fan. See Fan, page 9
